F(x) =2x+1 g(x) =x²-2x+2 tentukan fog, gof, gog, fof, gof (-2) ​

• (fog)(x)
= f(g(x))
= 2(x kuadrat – 2x + 2) + 1
= 2x kuadrat – 4x + 4 + 1
= 2x kudrat – 4x + 5

• (gof)(x)
= g(f(x))
= (2x + 1) kuadrat – 2(2x + 1) + 2
= 4x kuadrat + 4x + 1 – 4x – 2 + 2
= 4x kuadrat + 1

• (gof)(-2)
= 4 (-2) kuadrat + 1
= 4 x 4 + 1
= 17

Maaf aku nggak ngerjain yang (gog)(x) dan (fof)(x)

Semoga membantu
